Latin-American researchers, collaborating with the international community, have contributed in the last decades to sol-gelknowledge related to the generation of coatings on metallic bioimplants. Sol-gel technology allows the formation ofrelatively thin (1–2 microns) adherent, flexible and compact coatings that can be used as protection against corrosive mediaand for post-functionalization. Regarding low carbon surgical grade stainless steel, the application of silica-based sol-gelcoatings with different types of reinforcement and incorporating bioactive or antibacterial particles as a second phase,generates promising corrosion protection properties within physiological environments. In addition, they can preventinfections and stimulate bone formation/growth. This work explores the corrosion protection features provided by thinfunctionalized silica sol gel coatings to be used in orthopaedic devices.
